U.S. prosecutors are considering whether to pursue manslaughter charges against BP managers for decisions made before the explosion on the rig that killed 11 workers and caused the biggest offshore spill in U.S. history, a report from Bloomberg said, citing people familiar with the matter.

BP has admitted mistakes in the run-up to the rig blast but has denied accusations that it was "grossly negligent", a charge that could add tens of billions to the final bill it pays for the disaster.

Eleven deaths and immeasurable damage to the gulf, wetlands and wildlife. Not to mention the thousands affected financially by the mass exodus of rigs from the gulf since the spill. The local economy tanked. One year later BP is now allowed to drill in the gulf again.http://today.msnbc.msn.com/id/42400389/ns/business/
